Nádobka na ocní kapky obsahuje dnem opatrenou kónickou dutinu, vytvorenou v konci špicky telesa (A) nádobky, zhotoveného z termoplastového materiálu. Kapalina je naplnena a utesnena soucasne behem procesu vytvárení. Dutina vykazuje vnitrní prumer, zvetšující se smerem ke konci špicky nádobky. Dutina je tvarována tak, že kapací otvor (6c) o malém prumeru proniká dnem této dutiny pro regulování, na nastavené množství kapaliny vypuzované z telesa nádobky smerem ke dnu dutiny. Dno dutiny vytvárí konec špicky dutiny a je umísteno v zásobníku kapaliny, vytvárejícím prstencovitý prostor nádobky kolem dutiny. Zpusob výroby nádobky na ocní kapky probíhá stlacováním konvexní tvarovací formy (20) pro vytvárení dutiny (6b) ve smeru osy (x) nádobky a proti konci špicky telesa nádobky, pricemž kapalina je naplnena a utesnena soucasne behem tvarovacího procesu. The present invention relates to an eye drop container including a bottomed conical hollow formed in the tip end of the container body (A) formed from a thermoplastic material with a liquid filled and sealed therein simultaneously during the molding process. Said hollow having an inside diameter enlarging toward the tip end, and a small-diameter instilling hole (6c) penetrated through a bottom of the said hollow for controlling, at a set quantity, the liquid pushed out of the container body. The hollow bottom forms the end of the hollow tip and is disposed within a liquid reservoir forming an annular space of the container around the hollow. A method of manufacturing the above-described eye drop container comprises pressing, in the direction of a container axis (x) and against the tip end of the container body with the liquid filled and sealed therein simultaneously during the molding process, a convex forming die (20) for forming said hollow (6b), and a needle-like forming die for forming the said small-diameter instilling hole.
